Eco Design – Architects & Consultants  is an architectural practice which specializes in ecological friendly green building and consulting. Established in 1998 by Andy Horn, the practice has been at the forefront of the green building movement in South Africa and has won a number of international awards in the field of sustainable design.

Eco Design’s cutting edge sustainable solutions have been widely published both locally and internationally and have earned them the 2004 Sustainable Building Best Practice award for Residential Projects in the Africa Region  and the Silver Holcim Award for Sustainable Construction in Africa and the Middle East 2005.

Solving pressing issues locally

We have recently completed a revitalization project for a heritage site in Mamre near Cape Town. They not only used local materials, but also involved and empowered the community by providing public participation forums and running a series of training programmes.
By building in this sustainable way, Eco Design Architects managed to address two of the most pressing issues of South Africa: unemployment and environmental pollution.
